I am running an irt gpcm using svy, and I get the following error message
variable W_FSTUWT not found:
Here is what I know:
1. The variables W_FSTUWT W_FSTURWT1...W_FSTUWT W_FSTURWT80 are in the data file, as one can see from variable list on the right of the screen shot
2. If I run other svy commands, immediately before or after, on the same dataset, something like the mean, svy seems to work very well:
3. If I run irt gpcm immediately before or after, on the same variables and same dataset, including the weights [pw=W_FSTUWT], the model is estimated:
Any idea of what the problem is?
